I worked with Niki Doyle and the Huntsville Tennis Center to develop a small control panel that lets them indicate court status to their website visitors. It is easy to use on the backend and was easy to integrate into the frontend.
Sometimes a post or page is updated frequently for some reason. Perhaps it contains daily deals, site notifications or other things like that. The update subscription plugin I built allows individual users to subscribe to updates on a piece of content, confirm their subscription and receive notifications every time the content is updated. The users can also unsubscribe from the notifications at any time.
The Dealer Locator plugin allows my client to set up websites with an internal business directory and a “find by distance” search form. Without a doubt, this is one of the most successful plugins I’ve built as the client continues to use the solution 3 years later.
